At the head of Youzhou City, arrows rained down, mixed with the sound of stone bullets bombarding the city wall. The bed crossbow arrows used by the Song army are made of fine iron, and the strength is so great that they can shoot into the masonry, and the besieging crane army is also brave, and they actually connect the bed crossbow that is deeply rooted in the city with ropes, and then climb up like a tiger swimming in the wall. Because it is not a siege ladder used, when it is less than two or three zhang to the head of the city, if the Han soldiers defending the city do not lean out, they will definitely not see the Song army that is constantly climbing upward. For the sake of convenience, these warriors selected from the Crane Control Army only wore simple leather armor, shields and helmets, and tightly tied coarse cloth ropes in their mouths.

Seeing the soldiers who risked their lives to climb the city fall in twos and threes, even the Great Song Emperor Zhao Jiong, who was supervising the battle in the west of the city, had an unbearable look on his face, he had a gloomy face, and asked: "Is the internal should be safe in the Liao army?" Wang Yu, who was standing beside him, bowed and said: "Cai Zhalcan is a Hu man who lives in Youzhou, and he has won the trust of the Khitan and Han Derang, and the minister has made an appointment with him. Before Zhao Jiong's Northern Expedition, he was ordered to contact the Zoroastrian disciples in the Youyan area to secretly help the Song army, and the most important thing is to rely on the Liao army in the city to capture the southern city gate in one fell swoop.

Zhao Jiong nodded, his face was still gloomy, behind him, there were Pan Mei, Cao Han, Mi Xin and other important generals of the forbidden army, and then Shi Shouxin, Zhang Mei, Liu Yanrang and other generals, Anxi Jiedu made Wu Yingying also among them, everyone frowned and watched hundreds of crane control soldiers crawl towards the city little by little. Although this method of climbing with crossbow arrows to set up rope ladders is hidden and not easy for the enemy to detect, the speed of going up the city is also slow, once the enemy army finds it, it is immediately poured down with boiling oil, and none of the strong men who climb the city may not survive. Seeing that the time was passing little by little, the first Song army had climbed to only two feet below the city wall, and because they did not hear the movement of the city head, they clinged to the city wall and waited for the agreed signal.

At this moment, it was noon, and the June sun was shining on the city wall of Youzhou, and the soldiers could only squint their eyes, and the skin and flesh of the Song army who were like geckos climbing on the crossbow rope ladder were scorched. Wu Yingying couldn't imagine how those soldiers could endure the fear of death and the scorching sun at the same time. If he looked at it with the clairglass that Cai Jian had secretly made in his arms, he would find that the dark skin of all the climbers had a layer of coarse salt frost on their dark skin due to sweat, and some of them had cracked.

Diridu commanded Cai Zalcan to inspect the southern city with hundreds of his entourage, with a knife in his hand. The Song people's crane army carried the siege ladder in the morning and stormed for two hours, and finally abandoned more than 1,000 corpses and retreated. Seeing Di Li come up, Chang Wanshan, the commander of the Xiaowu battalion, nodded at him, wiped the blood marks on the iron knife, and said with a smile: "Cai Zhalcan, we Han people are here to fight to the death for the Liao State, but you Hu Chong are hiding behind, it is really hateful." "This Dilidu is an army composed of Xi people who live in Youzhou, and the Khitans trust him better than the Han soldiers. But in Youzhou, Xi Bing and Han Bing were both subordinates of An Lushan, the envoy of Youzhou and Lulong Jiedu in the previous dynasty, and they advanced and retreated together for hundreds of years, fought the Khitan together, and also fought the Central Plains, and the relationship between them was closer than that of the Khitans. Although the rebellion of An Lushan Shi Siming in the Tang Dynasty was finally settled, Youzhou has been separating itself from the Central Plains since then, and under the promotion of Zoroastrianism intentionally or unintentionally, Anshi is holy, especially in the army.

Seeing him scolding, Cai Zal Chan also replied: "Chang Wanshan, you have been waiting for the Han soldiers to disobey the Southern Dynasty for hundreds of years, don't think that the Southern Dynasty will not kill you when they come in." Although he walked forward while smiling, his hand had unconsciously pressed on the hilt of the knife at his waist, and the soldiers behind him also dispersed when they saw this, and approached the nearby Xiaowu Camp Han Army. Chang Wanshan didn't have it, and scolded with a smile: "Since An Sheng raised the army, when have we been afraid of the southerners? Why should we obey them?" Before the words fell, his eyes widened in disbelief, and his hands tightly grasped the back end of the blade that Cai Zhalcan pierced into his heart. Cai Zhalcan kills people like hemp, this knife is fast and accurate, Rao is Chang Wanshan and other fierce generals can't dodge, seeing that he has died, he sighed: "The Chang family also followed An Sheng to raise troops, for the sake of Zhongxing Shengjiao, I have to be sorry." While wiping the blood stains with the placket of his clothes, he sneered and watched the soldiers of Dilidu fight with the Han army of the Xiaowu camp at the head of the city.

The soldiers of the Xiaowu battalion did not expect that these Di Lidu soldiers, who drank together, looked for women together, and fought together in the grass valley, suddenly became a killer, and the commander made Chang Wanshan even more conspired at the first time, and was caught off guard, suffered a big loss, and more than 100 people fell in a pool of blood on the spot, and the rest of the people hurriedly drew their swords to resist and fought separately. Although there were more than 2,000 Han soldiers, they were leaderless, and on this section of the city wall, they were killed by hundreds of Dili and retreated.

When the Song army saw that a piece of white silk with a width of a foot was suddenly thrown down on the city wall, it was a pre-negotiated signal, and immediately turned the direction of the crossbow array that was constantly being released towards the city head, and launched it towards both sides of the west city tower, blocking the way for the Han army on the city wall to counterattack the city tower. The dead soldiers of the crane army climbing on the city wall can be regarded as waiting for the moment of attack, when they pulled out the sharp blade at their waist and put it in their mouths, they climbed up to the top of the city with their hands and feet, and cooperated with the Liao soldiers of Dilidu, and in a short time, more than 300 people went up.

Seeing that only three or four hundred Liao soldiers in the city tower who were still resisting stubbornly were solved, and the south city gate was within reach, Zhao Jiong was overjoyed, and couldn't suppress the excitement in his heart, and ordered loudly: "Don't miss the opportunity, once the city gate is opened, the iron cavalry and the Hujie army will quickly enter the city." Before he finished speaking, Cao Han had already ordered the 15,000 iron cavalry army and the 30,000 tiger army as a siege reserve, and saw that the army was rushing to the south gate of the fierce battle like a tide, just waiting for the city gate to open, Youzhou City would not belong to the Liao people, Zhao Jiong was extremely excited, and said loudly: "Beat the drums, help the strong men of the city, and recover Youzhou in a battle, it is a miracle!" Orr saw that the resistance of the Han soldiers in the city tower was very fierce, and he nervously watched the battle with the generals, frowning and said in a deep voice: "The thieves in Youzhou are so stubborn. The Hujie army quickly went to the city to help in the battle. At this time, the Hujie army had already set up a ladder in accordance with the established strategy of attacking the city, and climbed to the city with their hands and feet.

Just when everyone thought that the overall situation had been timed, the east side of the Xicheng Tower suddenly sounded the sound of Hu Ji, there was a Biao Khitan people and horses regardless of the arrows, with a shield to kill over, this team of Liao soldiers was very sharp, actually killed the soldiers of Dilidu retreated again and again, and soon fought with the Song soldiers who climbed the city.
